Preparation of functional currant-bun-like fumed silica/polymethacrylate nanoparticles by radiation-induced polymerization
Fumed silica (FS) is one of the few nanomaterials used in large scale in the production of several industrial products. In addition, the very low toxicity of these nano-sized particles led them to become excellent raw materials to develop novel applications in the field of downstream processing of b...
